EDWIN S. RICH, OF NEW YORK, NfY.

PORTABLE GAS=STAND.

SPECIFICATION forming part of Letters Patent N0. 390,70, dated October 9, 1888.

Application filed June 16, 1887. Serial No. 241,570.

To all whom, it may concern:

Be it known that I, EDWIN S. Rica, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Portable Gas- Stands, of which the following is a specification.

This invention has relation to gas-burners, and has for its object to provide a burner that may be used for eitherheating or lighting pur'- poses.

Further objects of the invention will hereinafter appear, and the novel features be particularly pointed out in the claims.

Referring tothe drawings,Figure l is a vertical central section of a gas-burner constructed in accordance with my invention, the parts being inposition adapted for heating. Fig. 2 is asimilar View, the parts being in position for illuminating; and Fig. 3 is a modification hereinafter described.

Like letters indicate like parts in all the ligures of the drawings.

A represents the base of the burner, upon which is mounted, by any suitable means, the tube B. which is provided with air openings or ports B about midway its length and with a vertical slot, B2. rIhe tube B is also provided with an annular ilange, B3, near its top, which projects outwardly and is'designed to support a chimney-supporting collar, B4.

Nithin the tube B is mounted a slidingtube, O, which is smaller preferably than the bore of the tube B, and is provided with annular outwardly-projecting tlanges O C2 at its top and bottom, respectively, which danges are in sliding contact with the tube B and serve to support said tube in slidingr position therein. From the flange O2 of the collar O and passing through the slet B'Z ol" vthe tube B there projects a lug, O, by which said tube may be raised and lowered within the tube B. Asetscrew, B5, passes through the tube B and bears upon and serves to maintain the tube O in an adjusted position within the tube.

rIhe upper end of the tube O is provided with a screw-threaded opeuing,O", into which is screwed an ordinary burner-tip, O5. rIhe lower end of the sliding tube O is also provided with a screw-threaded opening, O", into which is inserted a threaded and centrallyperforated plug, O7, the lower end of which is tapered and designed to receive one end of a iexible or other tube, D, the opposite end of (No model.)

which is connected with a chandelier, gasbracket, or other source of supply of gas.

Taking the parts in the position shown in Fig. l, the burner is adapted for heating purposes, the ring B L serving to support a kettle, pot, or other vessel. Vhen used as a heating device, the tube is in its lowest position, so that air may pass through the ports B in the tube B and commingle with the gas, thus intensifying the heat generated. By raising the tube O to its upper position, (shown in Figs. 2 and 3,) the ports B are cloned,and pure gas for illuminating purposes is burned, the tube being held in the desired position through the medium of the set-screw B5.

If desired, the slot B2 and lug O3 may be omitted, in which case a rod, O8, depends A may be formed in a single piece, and, as

shown in Figs. l and 2, said tube may be either screw-threaded into the base or held in place by means of ordinary screws or rivets.

Having described my invention and its operation, what- I claim isl. In a combined heating and illuminating burner, the combination of an outer heatingtube and an internally-sliding burner-tube,the latter being adapted to be drawn within the former when used for heating purposes and projected therefrom when used for lighting purposes, substantially as specified.

2. A combined heating and illuminating burner comprising an outer heatingtube having airports and an internal-sliding illuminating-tube adapted to close said ports, substan` tially as specified.

3. The base A, having the tube B mounted thereon and provided with the air-ports B', in combination with the sliding collar O, mounted in said tube and provided with the burner O5 and plug OT, substantially as specified.

4. The tube B, having ports B', in combination with the sliding tube O, having flanges O O2, removable tip O5, removable perforated lugs O7, and the pipe D, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 15th day of June, 1887.
